Hi! I'm trying to setup a cluster with 1 server and 2 agent nodes. I want to configure IPv4 and IPv6 dual stack, where IPv6 is the preferred one. I want to have an internal network for the nodes communication. It will be on OVH or Hetzner (traditional VPS and not managed). While OVH has IPv6 support on vRack, Hetzner only has IPv4 in the internal network. No load balancer for now. My questions are: 1. I only have /64 subnet for each node in each provider. I see that the cluster subnet should be /56 to have a /64 for each node. In this case should I use NAT6 with ULA? 2. Is it possible to have the IPv6 for outside and only IPv4 in the internal network? a. If yes, how can I customize the CDIR parameters (pods and services)?
